To all whom it maf conce'me: I i

Be it known that I, RAYMOND FISHER, a cRizen of the United States, residing at Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Automatic Stops for inding-Machines, ofwhich the;

following is a specification. 1 a

The lnventlon relates for wmdmgmachines and 1s illustrated as being applied to a yarn winding machine of, the type shownin Patent #1,120,438 issued to Brooks. The primaryobject of the invention is to provide means for preventing.

the gain movement when the yarn breaks, as

will be hereinafter pointed out.

Reference will be had to the accompany,

ing drawings forming a part of thisspecification and wherein hke numerals of referencedesignate corresponding parts throughout the several views, in which;

Fig. 2 is a plan or top view of the same,

of Fig. 2 and showing the parts in the inoperative Zosition, and Fig. 4 is a diagram illustrati g the laying of the yarn.

Beferr ng to the drawing, 2 is the winding spin ,e which may have imparted to it constantor variable rotary motion and 3 is the builder rail which reciprocates up and down and. carries with it the builder screw 4, bracket 12, and spring pressed pawl 13 which /intermittently causes partial rotation of the ratchet wheel 15 each time the builder rail 3 reaches the lower limits of its downward movements. Through the medium .of suitable gearing as disclosed in the said Brooks patent, the gain shaft 19 has similar rotative movements imparted to it from the said ratchet wheel 15.

.spring 30 in engagement with the threads of the builder screw to cause the gain-nut-gear when it is rotated to climb said builder Specification of Letters Patent Application filed February is, 1916. Serial No. 79,066.

screw, said arm 29 being disengageable with the builder screw threads manually to permit the gain nut-gear to be lowered when' it is desired to start a new bobbin.

As in the Brooks patent, the gain nut gear 25 has a depending hub on the lower eX-' tremity of which lock nuts 33 are placed and upon the, hub and held between said lock nuts and the gain nut-gear is a ring 34 pro- Vided with three arms 35, -36 and 37. A

guide rod 38projects upwardly from the builder rail ,in parallel relation with the builder screw. The said arm 36 mounts the yarn guide arm 40, and the arm 37 mounts another yarn gu1de-and also a tension device 42.- The yarn passes through the yarn guide 41, tension device 42 and yarn guide 40 to the bobbin on the spindle 2. I

patent. Referring The heavy lines indicate double yarn layers termed layer sets, each layer set comprising an up or progressive layer indicated by arrow P, and down or retroprogressive layer indicated by arrow B. The yarn guide traverses from elevation A to elevation A; B to B; C to C; and soon to completion of the bobbin. After it has gonefrom elevation A to elevation A and back to elevation A, the gain mechanism causes the gain nut-gear 25 to turn on the builder screw 4 and to step up the yarn guide so that the next traverse begins at B, the arrow G between elevation A and elevation B indicating the gain movement; this same gain movement is carried out the whole bobbin. The layers and layer sets are conical and are nested, the diagram showing the effect on only one side of the conical layers, the effect being the same elsewhere through any point in the layers or layer sets.

In the Brooks device, the spindle continues its guide its traverse, and if the operator, is not in constant attendance to cut the machine ofi' almost immediately the yarn breaks, the

if the yarn breaks,

gain nut-gear will have carried the yarn The stop lever 22 with its cams 11 and 21" 3 act, which is also true of the. parts thus far I described,,the same as in thesaid Brooks Figure 1 is a side elevation of yarn winding mechanism including the present im provements,

to the present improvements; 1 will first be had to the diagram in j on throughrotation, the yarn i gain isinposition f or the laying of layers .betweenelevations A and A" when the yarn breaks, if thema eli-ine is not immediately stopped, upon the-yarn being repaired, the

'laying willgbe in-the path upon resumption 'between the elevations C and C or even a higher path, instead of taking up somewhere either in the progressive or retroprogressive layers occurring between elevations A- and A where the yarn was winding when the break occurred. .-The'resul t in most .cases is thatthe package wound is worthless because of its unevenness and consequent imperfectbinding of the yarn coils relatively to each other.

-\Vith the present improvements, it is im-' material .wheth'er or not the operator is strictly in attendance to throw' the-lever 22 and thereby cut oil the movements of the machine. If the yarn, breaks, the gain mechanism will automatically be thrown out of operation and the continued traverse movement of the yarn guide and rotating of the spindle will be without efi'ect'upon the package being wound. For example, if the layer 7 set between elevations A and A is being woundand the break occurs at point S in the progressive layer, the spindle will continue rotationand the traverse motion or reciprocation of the builder rail will continue, both without any influence uponthe package, but on the other hand, the gain movement ceases immediately and automatically,

and, until the attendantis free to give his 'gressive layers of the layer set which was being laid (between elevations A and A).

when the break occurred. The 'efiect upon the package will be negligible whether the laying resumes at the same point in the traverse at which the break occurred,'so long at itresumes in the same or immediately succeeding layer without material intervening gain. In some cases, the gain movement Ymight take place just as the break occurs,

but even then the laying must resume with the immediately succeeding layer, though of the next succeeding-layer set, and this is immaterial in afiecting the product.

The improvements which produce stopping of this gain movement consists in providing the free end'of the" arm 3.5 with a transverse elongated opening 50 producing stops 51 and 52 connected. at theirouter por-. tions by portion 53, the last mentioned being unessential as the end of the arm 35 could merely be forked by employing only the stops 51 and 52 separated a distance greater than" the diameter of the embraced rod 38. The gain shaft 19 of the Brooks machine is out of mesh with the gain nut-gear 25, and

this resetting of said shaft necessitates modi- 'resetso that it's spur-gear 24 is at all times (l5 fication of the ca'm'portion 21 of the Brooks lever 22, and slight changes otherwise npt pertinent to the .subject matter herem claimed. The arm 35 is provided with a right-angular extension 54'on which is journaled a gear or. pinion 55 constantly enmeshed wlth the gain nut-gear andadapted to bo enmeshed with the driving 21.

' In operation, the .yarn passing through guide 41, tension 42 and guide 40 to the bobbin 6n the spindle 2, causes the yarnguide 40 to be pulled toward the bobbin and the stop 51 to engage with one side of the bar 38 and the gear or pinion 55 to enmcslr yarn breaking, there is nothing to longcr 'stop 52 engages withthe rod 38. Upon repair of the yarn, resumed feed thereof will cause the gear or pinion 55 to move in the direction of the arrow B in Fig. 3 'to again enmesh the pinion 55 with the driving gear 2 1. As long as the yarn is not feeding through the guides 40 and 41 and the tension' device 42, or in other words not pulling the parts so that they assume the positions in Fig. 2, the parts will be in the Fig. 3 position and because of the pinion 55 not imparting driving motion from the gear 21 to the gain nut-gear 25, the latter cannot progress along the builder screw and consequently as related to the gain movement, the yarn will resume laying substantially at the same point where it left off. Of course, as in Brooks, the stop lever 22 is available to the operator or attendant and this is thrown to cut ofl' the spindle and traverse movements while the yarn is being repaired.

What is claimed:

1. In a yarn winding machine, a builder screw, a driving gear, anut-gear mounted thereon, a pivotally mounted arm carried by the nut-gear, a yarn guide on, the arm and movable toward and-from the spindle, and means movable with said arm to engage and disengage the nut-gear from driving connection with the driving gear.

2. In a yarn winding machine, a winding spindle, a pair of parallel members, one of said members being threaded, a nut mounted on the threaded member, an arm pivotally mounted on one of said members and being carried with the nut, a yarn guide on'said arm and being movable by the yarn toward the spindle, a driving device, and a gear on Said arm in constant driving connection with 'said nut and in driving connection with said device only when the yarn guide is moved by the yarn in the direction of the spindle. I

3 In a yarn winding machine, awinding spindle, a rod, a builder screwrod parallel therewith, a nut-gear on the builder screw rod, means for ope 'ating said nut-gear, a yarn g'uide arm carried by the nut-gear and pivotally mounted, the pivotal axis thereof being coincident with the axis of the builder screw rod, said arm having stop portions residing on opposite sides of the first mentioned rod and spaced apart a distance greater than the diameter of the said rod, a gear carried by said arm and in mesh with the nut-gear, and a driving gear on the armmova-ble into and out of driving relation with said operating means for the nut-gear. 4. 'In a winding machine, a rod, means thereon adapted to progress therealong, a

' swinging arm carried bysaid means, a driv- ,meshed, the relation of said gears being such that upon release of the-arm due to breakage of the yarn the drive gear will force the arm gear out of mesh therewith.
